BLOCKING CHIMERIC ANTIGEN RECEPTORS FOR PREVENTION OF UNDESIRED ACTIVATION OF EFFECTOR AND REGULATORY IMMUNE CELLS

摘要

Provided herein are novel blocking chimeric antigen receptors ("bCARs") and immune cells (e.g., effector and regulatory immune cells) that express such bCARs. Such blocking CARs prevent undesired activation of the immune cells, particularly undesired activation of the immune cells against normal tissue in therapeutic applications. Thus, such bCARs advantageously allow for selective immune cell activation only upon interaction with specific target cells (e.g., tumor cell).
